Longitudinal changes in the spherical equivalent refractive error of children with accommodative esotropia

Area of Science:

• Ophthalmology
• Pediatric Ophthalmology
• Refractive Error Research

Background:

• Accommodative esotropia is a common form of strabismus in children.
• Refractive errors, specifically spherical equivalent (SE), play a crucial role in the development and management of accommodative esotropia.
• Understanding the long-term effects of spectacle prescription timing is essential for optimizing treatment outcomes.

Purpose of the Study:

• To investigate the longitudinal changes in spherical equivalent (SE) refractive errors in children diagnosed with accommodative esotropia.
• To determine how the age at which spectacles are prescribed influences the progression of SE refractive errors over time.

Main Methods:

• A longitudinal study followed 126 children with accommodative esotropia for an average of 4.4 years.
• Cycloplegic refractions were conducted using autorefraction or retinoscopy based on the child's age.
• Children were categorized into three groups based on their age at the time of spectacle prescription for analysis.

Main Results:

• Initial SE refractive error was found to be age-dependent, with higher errors in younger children (<2 years).
• All age groups exhibited an initial increase in SE refractive error, followed by a subsequent decrease.
• The timing of the peak SE refractive error varied significantly, occurring 1 year after spectacle wear in older children (4-8 years) and 6 years in younger children (<2 years).

Conclusions:

• The age at which spectacle wear is initiated is a critical factor influencing the longitudinal changes in SE refractive error for children with accommodative esotropia.
• These findings highlight the importance of individualized timing for spectacle prescription in managing refractive errors associated with accommodative esotropia.
